Application filed November 1, 1902. Serial No. 1291788. (No model.)

['0 (tZZ whom, it may concern:

Be it known that I, SWAN F. SwANsoN, a citizen of the United States, residing at Pueblo, in the county of Pueblo and State of Colorado, have invented certain new and useful Improvements in Railway-Oars; andI do declare the following'to be a full, clear, and exact de scription of the invention, such as will enable others skilled in the art to which it appertains to make and use the. same.

This invention has relation to railway-carfloor construction; and the object is to construct a supporting-framework for car-floors of steel, rail, or angle-iron bars which will combine great strength and durability with lightness.

A further object is to construct a car-floor of this character which may be adapted for use with freight or passenger cars, forming, therefore, a strong rigid foundation.

With these and other objects in view the invention consists in the combination and arrangement of the parts, as will be hereinafter more fully described and claimed, reference being bad to the accompanying drawings, in which- Figure l is a top plan view ofa car-floor, part of the floor-boards being removed to show the construction of the frame. Fig. 2 is a side elevation of the same. Fig. 3 is an enlarged cross-sectional view. Fig. 4 is a detail perspective view of a fragment of the frame, and Fig. 5 is a similar view showing a modified form cross-beam. V

In the drawings, 1 denotes the side plates of the frame, which are disposed-longitudinally along each side, the central portion of the plates, or that part lying between the trucks, being of greater width than the ends of the plates. 2 denotes channel-iron bars or rails bolted to the inner sides of the said plates to give rigidity to the same, as well as forming supporting-flanges upon whichthe ends of the car-floor boards are adapted to 4 denotes cross-bars preferably formed of hollow rectangular beams, the sides of which are extended and bent at right angles to the length of the beamto form attaching-flanges 4:, by which means the said beams are bolted at one end to the channel-rails 2 and at their opposite ends to the center sill 3.

5 denotes truss-plates arranged on each side of the cross-beams 4 and securely-bolted thereto at their ends. The central portions of the truss-plates are adapted to pass beneath the center sill 3, thereby rigidly bracing the same. 6 denotes a longitudinally-disposed plate arranged beneath the truss-braces 5 and immediately below the center sill 3 and forming a bearing-plate between the said truss-plates and the car-trucks.

'7 denotes a channel-iron having angularlybent edges forming flanges and is adapted to be arranged in the U-shaped center sill and to be bolted to the sides thereof to brace the same against lateral pressure.

8 denotes denotes longitudinally-disposed wooden stringers, one running adjacent to each side of. the center sill 3 and one running along parallel to the inner sides of the side plates. 1, adjacent to the channel rails 2. Said stringers are adapted to rest upon the cross-beams 4, which are arranged so as to bring the upper sides of the stringers flush or on a level with the top sides of the channel-rails 2 and the top side of the center sill, so that when .the. floor-boards 9 are placed across they will rest upon the channel-rails, stringers, and center sill and are held in place by nailing or otherwise securing them to the wooden stringers.

In Fig. 5 of the drawings I have illustrated a slightly 'different form of crossbeam l. In this'instance instead of employing a hollow rectangular bar I may substitute therefor a U-shaped or channel-iron bar having laterally-projecting flanges 4., upomwhiclithe stringers 8 may rest.

It will be seen-that the construction herein shown and described will insure a'substantial, rigid, and well-braced platform or support for a car floor and body and at the same time will be comparatively light in weight.

From the foregoing description, taken in connection with the accompanying drawings, the construction and arrangement of parts ICO will be readily understood Without requiring a further explanation.

Various changes in the form, proportion,

, and the minor details of construction may be resorted to Without departing from the principle or sacrificing any of the advantages of this invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a supporting-frame for railway-cars, the combination with the side and end plates, said side plates having longitudinally-disposed channel-iron brace-bars or rails bolted thereto, of a longitudinally disposed centrally-arranged center sill, transverse hollow beams connecting said center sill and said channel-iron bars or rails, transversely-arranged truss-plates fixed'at each end to the transverse beams near the outer ends thereof and extending beneath and supporting said center sill, a longitudinally-disposed bearingplate arranged beneath said truss-plates, and means for holding floor-boards in place upon said side rails and center sill, substantially as described.

2. In a supporting-frame for railway-cars, the combination with the side and end plates, said side plates having longitudinally-disposed channel-iron brace-bars or rails bolted thereto, of a longitudinallydisposed centrally-arranged channel-iron center sill,transverse hollow beams connecting said center sill and said channel-iron bars or rails, transversely-arranged truss-plates fixed at each end to the transverse beams near the outer ends thereof and extending beneath and supporting said center sill, a longitudinally-disposed bearing-plate arranged beneath said truss plates, and longitudinally disposed Wooden stringers adapted to rest upon said cross-beams whereby floor-boards may be supported and held in position upon said frame, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

SWAN F. SWANSON.
